Fish Oil you can trust to deliver consistent, meaningful health benefits
Our Fish Oil: Premium, Pure, and Proven
Not all fish oils are created equal. Questions around purity, sustainability, and effectiveness are common, and with good reason. Many products on the market don’t meet the high standards consumers deserve.
That’s why we sought out one of the world’s leading fish oil suppliers in Europe, whose oils are trusted for human consumption at the highest standard.
What Type of Fish Do We Use?
In our Lester's Oil, we use three types of fish: anchovies, sardines, and mackerel. These small, wild-caught fish are carefully chosen for very specific reasons:
Anchovies are naturally rich in omega-3 fatty acids and are one of the most concentrated sources of EPA and DHA available, making them a highly efficient base for a premium fish oil.
Sardines are packed with omega-3s and are known for their purity, as their short lifespan means they accumulate fewer toxins and heavy metals compared to larger fish.
Mackerel is one of the highest omega-3 containing fish in the world, contributing to the potency and effectiveness of every capsule.
As small, fast-reproducing fish, anchovies, sardines, and mackerel are among the most sustainable seafood choices available. Their ability to replenish quickly means we can source them responsibly without putting pressure on ocean ecosystems.
